Feature Capture
Queensland’s Digital Topographic Data has been collected from numerous sources over a long period of time with differing levels of accuracy and capture specifications. Historically, data was captured through photogrammetry for most relief and hydrological features. More recently, data for features have been collected through 2D digitising off existing mapping, photography, satellite imagery or manipulation of existing datasets to create new geographical dictionary or directory spatial data used to provide information about places, locations, and geographic features. The origin and accuracy of the source data is recorded in metadata and feature attributes.

These artificial features are crucial for geospatial data management , and analysis, and modelling, as they enable a more accurate representation of the real world and facilitate the extraction of valuable information from geospatial datasets. They allow for the efficient processing of data in a way that's meaningful and useful for various applications related to drainage networks and environmental studies.
